Hi All. Last year I bought a house, and in the garage was a fruit machine - Jolly Gems Model on a MPU4 board. The machine did not work. House restoration took priority, but I have recently got onto the machine. Removed the battery and cleaned and repaired a load of track, this allowed the machine to fire up but buttons did not work. Repaired some wire looms (mouse had been in!) and this allowed me to play. Works fine on demo, but when it comes to pay out it had issues,. ..had the 'OBTRUCTION ALARM'. traced this to no voltage to opto... Swapped a few triacs, transistors and caps round on the main board output section and hopper board and the opti was working again and switching fine. However, still did not payput because the hopper motor was not turning...started flashing up 'CALL MANAGER' on payout. Applied voltage to the hopper on its own and it worked so figured the hopper unit was OK. Did a bit more swapping of components and then had another error 'HOP COINSENSE ERROR' ....there is no voltage going to the opto again. The mainboard looks pretty nackered where the battery leaked and the components do too...I cant seem to track down where to but replaceemnts for each component so was looking to see if anyone had a spare (working) Mainboard MPU4 and hopper driver board to sell? Much appreciated! With thanks Barry.
